, 9]. A high copper recovery rate could be obtained through hydrometallurgical processes, but the waste leaching liquid presents a new form of environmental pollution [10]. Physical processes primarily... of copper oxides. Meanwhile, magnetic separation yields a low iron recovery rate because most iron exists in the form of fayalite (Fe2SiO4) in the copper slag [11]. In comparison, the pyrometallurgical......

water coning rate would be. Thus, it can reduce gas ultimate recovery. Bottom-water has a great effect upon fractured gas reservoirs, but gas well has little change if bottom-water size exceeded a certain extent. The higher gas pressure in fractured bottom-water gas reservoirs is, the greater coning rate would be. Thus, the higher the water-gas rate is, the lower gas ultimate recovery would be. Single......
